On 9 October 1962, the main streets in the center of Szczecin were closed to traffic. Inhabitants of the city crowded the sidewalks, curious to see the tanks and equipment of the three allied armies: the
Polish People's Army, the
Soviet Army, and the
National People's Army (NVA). Thousands of people, including children, gathered along Szczecin’s main arteries of Aleja Wojska Polskiego, Aleja Piastów, and Aleja Kościuszki. The event had been widely promoted, and schoolchildren were told to describe the parade as their homework. Students of all schools were allowed to go home early to spectate. Many children stood on the curbs as close to the tanks and other weapons as possible. City authorities adorned streets with flags of Poland, the Soviet Union, and East Germany; in schools, flowers had been given to children, who were told to wave them at soldiers. Newspapers headlines told readers that they would witness "A parade of our might", "A symbol of brotherhood in arms that serves the peace", and that "Polish Szczecin welcomes allied forces". The Warsaw Pact planners saw the parade as a show of the strength of its forces. It had been very carefully prepared, and Marshal Grechko wanted to present some of the best and most advanced weapons the Pact possessed in 1962. Thus, spectators had a chance to see cannons, mortars, armored personnel carriers, howitzers, and tanks. Above the city, a few heavy
Mi-6 helicopters flew, and warships of the
Soviet Navy lay moored in the port. First, tanks and weapons of the NVA appeared, followed by Soviet tanks, and finally, Polish units. Among them were 14 tanks of the from
Slubice. Crowds of adults and children alike came closer and closer to the vehicles, not listening to the
militsiya, who were telling them to move back. ==The tragedy==
